rawtoaces

rawtoaces is an open-source command-line tool and library for converting camera RAW images into the Academy Color Encoding System (ACES) scene-linear EXR files for professional motion picture and imaging workflows (color management / media processing).

  • Conversion of camera RAW images into ACES-compliant scene-linear EXR files (color management / media processing).
  • Implements camera-specific Input Device Transforms (IDTs) for supported digital cinema and still cameras (color management).
  • Provides a Command-Line Interface (CLI) for batch and scripted RAW-to-ACES processing (workflow automation / DevOps for media pipelines).
  • Integrates into visual effects, animation, and post-production pipelines that adopt ACES color workflows (media production pipelines).
  • Hosted under the Academy Software Foundation (ASWF) governance model for open-source media and entertainment tools (open-source foundation / governance).

More About rawtoaces

rawtoaces is an open-source utility focused on converting camera RAW image data into files encoded using the Academy Color Encoding System (ACES) (color management). ACES is a color encoding and management framework used in professional motion picture, visual effects, and post-production environments. rawtoaces addresses the requirement to ingest camera-native RAW formats and produce ACES-compliant, scene-linear OpenEXR files that downstream tools in a production pipeline can process in a consistent color space.

The project provides a command-line tool (workflow automation) that reads supported RAW image formats and applies camera-specific Input Device Transforms (IDTs) to Marketing Automation Platform (MAP) sensor data into ACES. These IDTs are defined according to ACES specifications and are tailored for specific camera models and vendors when available. The tool outputs OpenEXR files (image file format / high dynamic range imaging) encoded as ACES2065-1, which is the reference scene-linear encoding defined by the ACES system. This enables standardized, high-dynamic-range representations of captured images suitable for grading, compositing, and mastering workflows.

In enterprise or studio environments, rawtoaces commonly operates as part of automated ingest or rendering pipelines (media production pipelines). Facilities can script the rawtoaces CLI to batch-process dailies, VFX plates, or stills from supported cameras, ensuring that all material enters the pipeline already converted into a common ACES color space. This reduces the need for bespoke, application-specific conversion steps within each downstream tool, promoting consistency between departments such as dailies, editorial, visual effects, and color grading.

Technically, rawtoaces aligns with the ACES framework published by the Academy of Motion Picture Arts and Sciences (color management standard). It works within ecosystems that also use OpenEXR (image file format), OCIO-based configurations (color management), or other ASWF-hosted projects, although rawtoaces itself focuses specifically on the RAW-to-ACES conversion step. Its implementation relies on camera characterization data and IDT definitions that are maintained to match ACES guidelines, so that the output EXR files can be reliably interpreted by any ACES-aware application.

From an enterprise IT and pipeline architecture perspective, rawtoaces fits into categories such as color management utilities, media processing components, and command-line tools for content preparation. It is suitable for integration into production render farms, asset management systems, and ingest services that need deterministic, scriptable RAW conversion. Governed under the Academy Software Foundation (ASWF), it is developed and maintained in alignment with industry practices for open-source software in media and entertainment, and is positioned as a specialized component in ACES-based digital imaging workflows.
